Sorry to hear that (actually the first time I read ADHD) but I am glad music is able to keep you focused. Nothing better than that. I am a heavy music listener too and music keeps me fresh and relaxed. Problem is I am often sucked into music and enjoy it and lose focus on other things. LOL When I have some serious deadlines I have to refrain myself from listening to music and focus on the task. Unfortunately I can't handle both at the same time.
I can understand the importance of your audio rigs to you. As I used to say, they have grown to become my body parts.
There have been air-drumming incidents at work where I suddenly became the entertainment for the rest of the office while trying to keep up with Christoph Schneider on my imaginary drums
